Complete Savings Charging my credit card for membership I never signed up Internet

CompleteSavings obtained my credit card information from TigerDirect internet store. After my purchase from TigerDirect I received a few emails from CompleteSavings that were ignored by me because I didn't have any business with this company. I realised that my credit card was charged more than one year by CompleteSavings for membership I never signed for. Since they charge $12 per months most of other people start to pay attention to this small sum only a few months later like it happened to me. Considering huge volume of sales done by TigerDirect every day they make uncontrolled amount of money charging customers for membership. I didn't enter my credit card or any other information and even didn't visit CompleteSavings website till today when found out about strange monthly charge of the credit card. CompleteSavings set-up account for me using  information provided to TigerDirect and started to charge my credit card. Be carful to make purchase with TigerDirect also - they started to use another company probably the same way. All savings with companies like CompleteSavings or TigerDirect is ripoff. i purchased 2 items with $25 value and additionaly lost $192 plus must cancel my credit card. TigerDirect was absolutely sure that there is no way for me to proof this fraud because they can easy proof that I signed up for membership myself.  Probably they can generate any kind of proof from their website.
